Jennifer Lopez
You can also call her...
J. Lo
Age: 41

Why she got the gig:
She has tons of experience in the music industry — and that tends to help when you're judging a talent competition. She's also one of Hollywood's most famous actresses, as well as a tabloid target who's kept gossip-loving fans buzzing for years. ('Memba the days of "Bennifer"?) Bottom line, it'll be pretty darn cool to have a movie star/pop diva sitting at the judges' table every week.

A few Jennifer Lopez songs you might have bumped in your car: "Jenny from the Block," "I'm Real," "Love Don't Cost a Thing"

Jennifer Lopez movies you might have seen: The Wedding Planner, Selena, Made in Manhattan

Personality points: She's "Jenny from the Block," a girl from the Bronx who can relate to young contestants who want to make it big. She'll be the sweetest judge at the table — but with just enough Bronx spice mixed in.

Her thoughts on joining Idol: "I'm loving it. It's so much fun," she told the hosts of The Talk. "I did it because I thought it would be fun and I'd get to be in one place… when it goes live, I'll be home for like five months, which is great."

Personal life: Jennifer and music star Marc Anthony are the parents of twin siblings Emme and Max. Jennifer and her family split their time between Los Angeles and New York.

Steven Tyler
Age:
62

Why he got the gig: Well, duh! Steven is a rock icon adored by countless fans around the world — and his band Aerosmith has sold more than 100 million albums since they released their eponymous debut record in 1973. With some of the most popular Idols in recent seasons being rockers themselves, it’s the perfect time for a rock star to join the judges' panel.

A few Steven Tyler songs you might have rocked out to: "Dream On," "Walk This Way," "Come Together"

Personality points: Fans are familiar with his on-stage rock star persona. And off-stage, Steven Tyler has been called witty and entertaining. Let's hope we get a taste of that wit each week on American Idol!

His thoughts on joining Idol: "It's being a part of something much bigger than yourself… I want to bring some rock to this roller coaster," Steven said at a press conference to announce the new judges.

Personal life: Steven is a twice-divorced father of four, including Armageddon actress Liv Tyler. Steven has struggled with drug abuse throughout his life, but he is reportedly clean and sober after completing his last stint in rehab for abusing painkillers in 2009.
